Description

Technical Field

[0001] The present invention relates to the technical field of aluminum plate processing, in particular to a plasma cutting machine for aluminum plates. Background Art

[0002] The principle of a plasma cutter is to utilize the high energy density and instantaneous high temperature of plasma to melt metal materials, enabling processes such as cutting and welding. During the cutting process, a plasma gun generates an arc discharge through a power supply, ionizing gas atoms to form plasma. The high energy density and instantaneous high temperature of the plasma instantly melt the metal material and form a high-speed gas flow, achieving the purpose of cutting the metal. Plasma cutters are often used in the processing and cutting of aluminum sheets.

[0003] For example, patent publication number CN116117290A, titled "A Plasma Cutting Machine for Cutting Metal Sheets into Multiple Shapes," includes a mounting platform, a movable mechanism disposed on the movable mechanism, a plasma cutting mechanism disposed on the movable mechanism, a first water spray dust removal mechanism connected to the movable mechanism, a grinding mechanism disposed on the plasma cutting mechanism, and a metal sheet fixing mechanism connected to the ground disposed below the plasma cutting mechanism. The movable mechanism drives the plasma cutting mechanism to move in multiple directions, and then cooperates with the metal sheet fixing mechanism to achieve automatic multi-shape cutting of metal sheets.

[0004] However, during the use of the above document, the metal sheet needs to be placed on the placement rack first, so that the clamping plates can fix the aluminum sheet, and then the metal sheet can be cut. After the cutting is completed, the metal sheet can be removed. Since the aluminum sheet is located between the clamping plates, the operator needs to move the metal sheet upward over the clamping plates on the placement rack during the process of placing the metal sheet on the placement rack and removing it after cutting. This is more laborious and inconvenient to operate, especially when it is necessary to move heavier metal sheets for loading and unloading. Summary of the Invention

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 5As shown, a plasma cutting machine for aluminum plates includes a support frame 1. The support frame 1 is U-shaped, and support legs 2 are fixedly installed at the four corners of the bottom of the support frame 1 to support the entire device. A gantry frame 3 is slidably installed on the top of the support frame 1. The gantry frame 3 includes two vertical plates 301. The top of the support frame 1 is provided with two symmetrically arranged guide grooves 4 along its length extension direction. The bottoms of the two vertical plates 301 are respectively slidably mounted in corresponding guide grooves 4. A horizontal plate 302 is fixedly installed between the tops of the two vertical plates 301. A first drive assembly is installed on the gantry frame 3 to drive its horizontal movement. The first drive assembly includes a first motor 5 and a drive rack 6. The first motor 5 is fixedly mounted on one of the vertical plates 301 of the gantry frame 3. A drive gear 7 is fixedly installed on the output end of the first motor 5. The drive rack 6 is fixedly mounted on the top of the support frame 1 along the length extension direction of the support frame 1, and the drive rack 6 is meshed with the drive gear 7. When the first motor 5 drives the driving gear 7 to rotate, the driving gear 7 engages with the driving rack 6 to drive the gantry 3 to move along the guide groove 4, thereby facilitating the cutting of the aluminum plate.

[0025] like Figure 1 As shown, a connecting plate 8 is slidably mounted on the horizontal plate 302 of the gantry 3. A plasma cutting machine body 9 is fixedly mounted on the top of the connecting plate 8. A cutting nozzle 10 is fixedly mounted on the bottom of the connecting plate 8. The cutting nozzle 10 is connected to the plasma cutting machine body 9 via a hose. A third chute 11 is provided on one side of the horizontal plate 302 along its length. A third threaded rod 12 is rotatably mounted in the third chute 11. Both ends of the third threaded rod 12 are polished rods. The polished rod sections at both ends of the third threaded rod 12 are respectively inserted into the horizontal plate 302 and rotatably mounted with the horizontal plate 302. A third motor 13 is fixedly mounted on one end of the horizontal plate 302. The output end of the third motor 13 is inserted into the horizontal plate 302 and is coaxially fixedly connected to one end of the third threaded rod 12. A third slider is threadedly connected to the third threaded rod 12. The third slider is slidably mounted in the third chute 11, and one side of the third slider is fixedly mounted in the connecting plate 8. (The sliding engagement of the third slider with the third chute 11 is conventional technology and is not shown in the accompanying drawings.) The first motor 5 and the third motor 13 are controlled by a PLC program, which can control the forward and reverse rotation of the first motor 5 and the third motor 13. The first motor 5 drives the gantry 3 to move left and right, and the gantry 3 drives the cutting head 10 to move left and right. The second motor 15 drives the cutting head 10 to move forward and backward, thereby enabling the cutting head 10 to move in multiple directions, thereby meeting the requirements for cutting aluminum sheets into various shapes.

[0026] A movable rack 14 for placing aluminum plates is slidably installed in the support frame 1. The movable rack 14 includes a U-shaped frame 141. The opening direction of the U-shaped frame 141 is consistent with the opening direction of the support frame 1. A plurality of equally spaced placement plates 142 are fixedly installed in the U-shaped frame 141 to facilitate the cutting of the aluminum plates. The debris and dust generated by the cutting fall to the bottom of the movable rack 14 through the gaps between the placement plates 142 during the cutting process.

[0027] like Figure 2 As shown, the support frame 1 is equipped with a second drive assembly that drives the mobile frame 14 to move horizontally. The second drive assembly includes a second motor 15 and a second threaded rod 32. A second slide groove 31 is provided on the inner side of the support frame 1 along its length extension direction. The second threaded rod 32 is rotatably installed in the second slide groove 31. The light rod sections at both ends of the second threaded rod 32 are respectively passed through the support frame 1 and are rotatably installed with the support frame 1. The second motor 15 is fixedly installed on the left side of the support frame 1. The output end of the second motor 15 is passed through the support frame 1 and is coaxially fixedly connected to one end of the second threaded rod 32. The outer periphery of the second threaded rod 32 is threadedly connected to a second slider 33. The second slider 33 is slidably installed with the second slide groove 31, and one side of the second slider 33 is fixedly installed with the U-shaped frame 141 of the mobile frame 14.

[0028] like Figure 1 As shown, a first chute 19 is defined on a side of the support frame 1 opposite the second chute 31. A first slider 18 is slidably mounted within the first chute 19. The first slider 18 is fixedly mounted and engaged with the U-shaped frame 141 of the mobile frame 14. The second motor 15 drives the second threaded rod 32 to rotate. The rotation of the second threaded rod 32 drives the mobile frame 14 to move via the second slider 33. The movement of the mobile frame 14 drives the first slider 18 to move along the first chute 19, thereby making the mobile frame 14 more stable during movement.

[0029] like Figure 1 and Figure 3 As shown, a push plate 16 is slidably mounted on the top of the movable frame 14, and the push plate 16 is adapted to the size of the interior of the U-shaped frame 141. The two ends of the push plate 16 are respectively slidably mounted on the inner side of the U-shaped frame 141. A movable rod 20 is fixedly mounted on the bottom of the push plate 16. The movable rod 20 is located between two adjacent placement plates 142. The movable rod 20 extends downward to the bottom of the placement plates 142 and is fixedly mounted with a first rack 21. A first mounting plate 23 is fixedly mounted on the bottom of the U-shaped frame 141, and a first rotating shaft 24 is rotatably mounted on the first mounting plate 23. The first rotating shaft 24 is horizontally inserted into the first mounting plate 23, and one end of the first rotating shaft 24 is fixedly sleeved with a first gear 22 that meshes with the first rack 21. A second rack 26 is fixedly mounted on the bottom of the support frame 1, and the other end of the first rotating shaft 24 is fixedly sleeved with a second gear 25 that meshes with the second rack 26 when in contact.

[0030] like Figure 3 、 Figure 4 and Figure 5 As shown, a baffle 17 is movably mounted on one end of the U-shaped frame 141, and an opening and closing assembly that drives the baffle 17 to open and close is symmetrically mounted on the U-shaped frame 141. The opening and closing assembly includes a fourth slider 37. A fourth slot 38 is horizontally opened on one side of the U-shaped frame 141. The fourth slider 37 is slidably mounted in the fourth slot 38. A fifth slider 39 is also slidably mounted in the fourth slot 38. A hinged rod 40 is hingedly mounted on the fifth slider 39, and the other end of the hinged rod 40 is hingedly connected to the fourth slider 37. A connecting rod 41 is fixedly mounted on one side of the fifth slider 39, and the other end of the connecting rod 41 is fixedly mounted in conjunction with the baffle 17. A second mounting plate 28 is fixedly mounted on the bottom of the U-shaped frame 141. A second rotating shaft 29 is horizontally rotatably mounted on one side of the second mounting plate 28. The outer periphery of the second rotating shaft 29 is fixedly sleeved with a third gear 30 and a fourth gear 34. The bottom of the support frame 1 is fixedly installed with a third rack 27 that engages with the third gear 30 when in contact. A fifth gear 35 that engages with the fourth gear 34 is rotatably installed on one side of the U-shaped frame of the movable frame 14. The bottom of the fourth slider 37 is fixedly installed with a fourth rack 36 that engages with the fifth gear 35. The fourth rack 36 is slidably fitted with one side of the U-shaped frame 141.

[0031] like Figure 5 As shown, a downwardly inclined fifth chute 42 is defined on one side of the U-shaped frame 141. The fifth chute 42 communicates with the fourth chute 38, and an angle is formed between the fifth chute 42 and the fourth chute 38, with the angle being greater than 120 degrees and less than 150 degrees. This facilitates the smooth sliding of the fifth slider 39 along the fifth chute 42 into the fourth chute 38. The connection between the fourth and fifth chute 38, 42, is an arc-shaped transition. The fifth slider 39 is a rectangular parallelepiped structure, and the corners of the contact with the arc-shaped transition at the connection between the fourth and fifth chute 38, 42, are all arc-shaped, facilitating the smooth sliding of the fifth slider 39 from the fourth chute 38 into the fifth chute 42. When the fifth slider 39 slides into the fifth chute 42, it rotates, driving the baffle 17 downward via the connecting rod 41 to prevent the baffle 17 from obstructing the aluminum plate as it is placed on the movable frame 14.

[0032] Working principle:

[0033] During use, an aluminum plate is placed in the U-shaped frame 141. At this time, one side of the aluminum plate abuts against the push plate 16, and the other side of the aluminum plate abuts against the baffle 17. The first motor 5 is started, and the output end of the first motor 5 drives the driving gear 7 to rotate. The driving gear 7 engages with the driving rack 6 to drive the gantry 3 to move left and right. At the same time, the third motor 13 is started, and the output end of the third motor 13 drives the third threaded rod 12 to rotate. The rotation of the third threaded rod 12 drives the connecting plate 8 to move. The connecting plate 8 drives the plasma cutting body and the cutting nozzle 10 to move back and forth, so that the cutting nozzle 10 moves in multiple directions to cut the aluminum plate, thereby meeting the demand of cutting the aluminum plate into various shapes.

[0034] After the aluminum plate is cut, the second motor 15 is started, and the output end of the second motor 15 drives the second threaded rod 32 to rotate. The rotation of the second threaded rod 32 drives the second slider 33 to move right, and the second slider 33 drives the U-shaped frame 141 to move right, and the U-shaped frame 141 drives the second mounting plate 28 to move, and the second mounting plate 28 drives the second rotating shaft 29 to move. The second rotating shaft 29 simultaneously drives the third gear 30 and the fourth gear 34 to move, and the third gear 30 engages with the third rack 27 to rotate. The third gear 30 drives the fourth gear 34 to rotate through the second rotating shaft 29, and the fourth gear 34 drives the fifth gear 35 to rotate, and the fifth gear 35 drives the fourth rack 36 to move right, and the fourth rack 36 drives the fourth slider 37 to move right along the fourth sliding groove 38, and the fourth slider 37 drives the fifth slider 39 to slide along the fourth sliding groove 38 through the hinged rod 40, and the fifth slider 39 drives the baffle 17 to move right through the connecting rod 41, thereby opening the baffle 17 to prevent the baffle 17 from subsequently hindering the aluminum plate from moving right. When the fifth slider 39 enters the fifth slide groove 42 along the fourth slide groove 38, the fifth slider 39 rotates in cooperation with the fifth slide groove 42, so that the fifth slider 39 drives the baffle 17 to rotate downward through the connecting rod 41, preventing the baffle 17 from obstructing the unloading of the aluminum plate.

[0035] When the fifth slider 39 abuts the bottom wall of the fifth chute 42, the third gear 30 disengages from the third rack 27. At this point, the second gear 25 meshes with the second rack 26, and the U-shaped frame 141 continues to move rightward. The U-shaped frame 141 drives the first mounting plate 23 to move, which in turn drives the first rotating shaft 24 to move. This first rotation simultaneously drives the first gear 22 and the second gear 25 to move. The second gear 25, meshing with the second rack 26, drives the first rotating shaft 24 to rotate. The first rotating shaft 24 drives the first gear 22 to rotate, which in turn drives the first gear 22 to move the first rack 21 rightward. The first rack 21 drives the push plate 16 to move rightward, which in turn drives the cut aluminum sheet rightward, thereby pushing the aluminum sheet out of the U-shaped frame 141, making it easier for the operator to remove the aluminum sheet. When the push plate 16 moves rightward to its maximum limit, the second gear 25 and the second rack 26 continue to mesh.

[0036] When loading the aluminum plate, the operator can place one end of the aluminum plate on the placement plate 142 and at the same time place the aluminum plate on the top of the baffle 17, so that the baffle 17 supports the aluminum plate, thereby saving manpower, and then push the aluminum plate to slide to the left and abut against the push plate 16, and then start the second motor 15, the second motor 15 reverses to drive the second threaded rod 32 to rotate, the second threaded rod 32 drives the U-shaped frame 141 to move to the left through the second slider 33, the U-shaped frame 141 drives the aluminum plate and the first mounting plate 23 to move to the left, the first mounting plate 23 drives the second gear 25 to move to the left through the first rotating shaft 24, the second gear 25 drives the first rotating shaft 24 to rotate under the action of meshing with the second rack 26, the first rotating shaft 24 drives the first rack 21 to move to the left through the first gear 22, and the first rack 21 drives the push plate 16 to move to the left through the moving rod 20, so that the push plate 16 will not hinder the subsequent left movement of the aluminum plate. When the push plate 16 abuts against the left side of the U-shaped frame 141, the second gear 25 is disengaged from the second rack 26, and the third gear 30 is engaged with the third rack 27. Then the U-shaped frame 141 continues to move to the left, and the U-shaped frame 141 drives the second mounting plate 28 to move to the left. The second mounting plate 28 drives the third gear 30 and the fourth gear 34 to move at the same time through the second rotating shaft 29. Under the action of the third gear 30 meshing with the third rack 27, the second rotating shaft 29 is driven to rotate, the second rotating shaft 29 drives the fourth gear 34 to rotate, the fourth gear 34 drives the fifth gear 35 to rotate, the fifth gear 35 drives the fourth rack 36 to move to the left, the fourth rack 36 drives the fourth slider 37 to move to the left, and the fourth slider 3 The fifth slider 39 is driven to the left by the hinged rod 40. The fifth slider 39 then drives the baffle 17 to move via the connecting rod 41. When the fifth slider 39 enters the fourth chute 38 from the fifth chute 42, the fifth slider 39 rotates and simultaneously drives the connecting rod 41 to a horizontal position. The connecting rod 41 then drives the baffle 17 to contact the front side of the aluminum plate. The U-shaped frame 141 then continues to move leftward, thereby driving the fifth slider 39 to slide along the fourth chute 38. The fifth slider 39 drives the baffle 17 to the left via the connecting rod 41. The baffle 17 pushes the front end of the aluminum plate, driving the aluminum plate to the left. When the rear side of the aluminum plate abuts the push plate 16, the baffle 17 precisely abuts the front end of the U-shaped frame 141, completing the loading of the aluminum plate. The baffle 17 and the push plate 16 simultaneously position the aluminum plate to prevent it from moving during the cutting process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
